protuberant
UK: /prəˈtjuːbərənt/ | US: /proʊˈtuːbərənt/
adj. bulging or swelling outward; protruding
The word "protuberant" originates from Latin protuberare, combining pro- (forward) and tuber (a swelling or lump). The root tuber also gives us words like "tubercle" (a small rounded projection) and "tuberosity" (a large protrusion in bone anatomy). The suffix -ant turns the verb into an adjective, describing something that "swells forward." The term vividly captures the image of a surface pushing outward, often used in biology or anatomy to describe bulging structures.
